My invention 'relatestoroofs for railway cars and. more particularly to steel roofs therefor comprising a plurality of metal sheets associated with :a car superstructure of metal carlines. l

Ihe principal object of the invention'i-s to so construct a roof of'this type that it may be eificientlyinsulated; f 1 f A primary feature of the invention con- -g sists in providing a carroof of thetype involving a pluralityof carlines and roof sheets disposed therebetween, with insulating materialspanning the spaces between ithe'carlines Another feature of the invention resides in providing a car roof of the type involving a plurality of carlines and roof sheets spanning the spaces" between the carlines, with sheets of insulating material respectively interposed between the carlines and underlying the roof sheets, said "roof sheets being supported by the carlines through the interme diacy of the insulating sheets. y

A further feature of the invention consists in providing a carroof-of the type involving a plurality of carlines having roof sheets spanning the spaces between them," with I sheets of insulating material interposed be-V 80 tween and supported by the carlines and-un derlying the roof sheets, and with'additiona'l sheets of insulating material underlying the carlines and extending substantially continuously from oneside of the'carto the other sides in associating with a car .roof of the type having a :plura'lityof carlines each provided with laterally projecting flanges, sheets of .g insulating material respectively interposed between the carlinesf and supported :by the lateral flanges thereof androof sheets oven lyingand supported bysaid insulating sheets.

Referring more particularly to the draw :i-ngs 1 indicates the side plates of thecar roof frame, each of which is preferably Z-sha-pBd :having a substantially vertical web- 2 and-op- 7 positely projecti-ng'horizontal flanges "3 and tially channel-shaped carl'ines 5, each being advantageously fashioned wth a top'web portion G and downwardly diverging sidesplates lby -anyy-suitablemeans; I

Spanning the spaces %between the carlines' .4, respectively; Extendingtransversely of the car are a plurality of inverted 'substa-nedges of {the roofsheets wooden fillers 10 may: 1 be conveniently interposedfbetwe'en them and" the horizontal flanges 3 of the side plat-es, the'woo'denfillersbeing secured to the. side plates by bolts' ll, 7

roof sheets is ofiiset as at 12 and "terminates Adjacent their marginal ea eseachai the short of the respective sidesof the cooperating carlines in upwardly projecting flanged portions 18. Embracing each of the carlines is a substantially trough-shaped seam cap 14 which,if desired, may extend continuous flanged as-atw18"for engagement" witlrthe off set portions 12 of the roof sheets. The

flanges 18 of the seam caps and the offset" portions 12 of the roof are so formed 2116116 lated that when the seam caps are secured in plaCe the'fjflanges' 18 xthereofrexert a down- .ward pressurezuponithe roof sheets "A plurality of clamps 19 are employed for rigidly securing the seam caps 14 to'thecarlines. Each clamp is fashioned with downwardly diverging sides "21, the divergence of the sides of the;clamps normally being somewhat less thanthe divergence of the sides of the carlines so that when the clampsare drawn downwardlythe sides of the seamcaps are forcedinto wedgingengagement with the sides-ofthe clamps. wln the preferred embodimentof the invention each of the clamps is shown as being provided with a bolt. 22

which depends downwardly from? the web thereof through an aperture formed in the web 6 oflthejccarlinea Disposed withinreach of the ca'rlines area; plurality of wooden fillers 23 respectively adjacent the clamps 19 which are apertured to receive thebolts 22 of thelatter: I The portion of each of the filler blocks 23 adjacent the end of the bolt of the associated clamp is cutaway as at- 24 to form a recess for receivinga nut;25 having thread- "ed engagementfwiththe lower end of the bolt.

, Another means for securing the clamps; in place is illustrated in F igurefiof the drawings. In this case each of the clamps is pro vided with} a depending :bolt 26,;provided with an elongated slot forgreceiving a wedge key.27.-" j The key is. formed so thatafter it has been driven into, place its ends maybe spread apart to prevent it' 'from being accidentally displaced fromfcooperative association withthe clamp. In order maintain a, somewhat even temperature therein" insulat ng material is; interposed between the {carlines and roof' sheets 7 on the one handv and the inside of the car on .the other. The insulating-material is pref;-

erably formed in sheets28 and 29 and-Vmay be of any. suitable material such as celotex,"

beaver-board or their equivalent. A' sheet to prevent sudden changes of temperature *within' the car and toof this material is interposed between each of the carlines and preferably extends continuously therebetween and between the side plates in engagement with the underside of the associated roof sheet. The side marginal edges of the insulating sheets 28 overlap pingly engage and restupon the lateral base flanges 8 of the carlines. The insulating sheets 28 are made so as to possess ,suflicient stiffness and rigidity to form, with the exceptionof the fillers 10, the sole. support for theroofsheets 9. In this manner the usual .purlins and ridge pole of the car roof construction may be eliminated. 1 The sheets 28 are clamped' b'etween the lateral base flanges of the 'c'arlines'and the roof sheetsby the downward pressure exerted on the roof sheets by'the seam caps 14. When a relatively soft or porous; type of insulation is used the compression thereof may be limited by interposingIfillers-30 between the lateralflanges of the carlines 'and the offset portions 12'of the roof sheets as clearly shown in Figure 5. It

'will, of course,'be appreciated that although the insulation may be relatively soft or porous it'will still have sufficient rigidity to support the'roof sheets. J

The undersides of the carlines are insulated by the sheets 29 which are of a width substantially equal to the base of thecarlines and which extend preferably continuously from one side plate to the other;. These insulating sheets engage theundersides' of the lateral base flanges of thecarlin'es and are preferably secured in place by any suitable means such as nails 31 which pass through the in sulation into the filler blocks 23 within the carlines. YA nailing strip 32' may advantageously be employedto prevent the securing nails 3-1'froin tearing or otherwise injuring the insulatingv sheets 29 and thereby enable the sheets to move out of engagement with the undersides of-the carlines. a

Figure 6 illustrates a manner in which the insulating sheets 28 and 29 may be supported when a securingclamp of the type illustrated therein-is employed. As clearly shown, the insulating sheet 29 engages the undGISlQlQ of and is secured to the lateral base flange 8 of the carlines by 'any suitable; means,

such as bolts 33 which pass through the flanges and insulating sheets. The lateral base flangesof the carlines illustrated in Fig. ure 6 are not asfwid'e asfthose of the carlines illustrated in Figures 1 to 5, inclusive, of the drawings so that the insulating sheets 29 may project a relatively great distance beyond their edges. Theinsulating sheets 28 instead. of overlappingly engaging the base flanges of the carlines as'he'retofore described over? lap and-are supported by'the projecting portions of the'insulating sheets 29. Thus'in bothf case's'theinsulating sheets 28 aresupported by the-carlines ;'-in Figures 1 to 5-, in-

clusive,;being supporte'd dire'ctlythereby due I to their overlapping engagement with the base flanges of the carlines and in Figure 6, indirectly thereby due to their overlapping engagement with the insulating sheets 29 which are directly carried or supported by the base flanges. roof sheets are supported by the carlines through the intermediacy of the insulating sheets.

From the foregoing it will be perceived that not only does the insulation employed efiiciently perform its intended function but that the manner in which it is associated with the carlines and roof sheets eliminates the use of purlins and ridge poles heretofore necessary in flexible roofs of the type herein disclosed. Although a roof of the flexible type has been chosen for illustrating the invention those skilled in the art will readily appreciate that the invention is not limited in its ap plication to this style of roof but that it may be applied equally as well to other types of roofs wherein the roof sheets are associated with the carlines.
